Since I'm endlessly chasing this noise in my motor, and the bikes been underwater, and it's got 84000 on the clock I've decided the old girl deserves a full rebuild.
There's a cheap 0.5mm (64.5) oversized piston kit available for them, but has anyone gone bigger than that? I can get a pair of pistons made reasonably cheap through work. How big can I go without swapping out the barrels so I can keep the 400cc stamped ones as my local track has a 400cc class
